OFFSET CHUCK AND ADJUSTABLE STAY LOG.

Application filed August 2, 1924. Serial No 729,820.

T all whom it may concern:

Be it known that I, CLARENCE A. Knssmiu,

a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Offset Chucks and Adjust-able Stay Logs; and I do declare the following to be a full, clear, and exact description of the invention, such as 9 will enable others skilled in the art to which 'its appertains to make and use the same, reference being had to. the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to an ofiset chuck and adjustable stay log to be used in connection with a veneerinp; machine, the primary object being to provide a stay log; to which the wooden log may be conveniently attached without the necessity of cutting away part of the log and without the necessity of fastening the stay log to the wooden log by the inconvenient methods now generally practiced.

The invention consists in certain novel parts and combinationsof parts, all of which will be specifically referred to hereinafter, reference being; had to the accompanying drawings, in which Fig. 1 is a perspective view of a conven tional form of veneeringmachine to which my invention is applied.

Fig. 2 is a sectional view of one of the stay log brackets and one of the chucks.

Fig. 3 is a perspective view of one of the stay log brackets, and

Fig. 4- is a sectional View through the log showing the stay log fixed to the log.

' The veneering machine may conform to standard practice. It is designated by the reference numeral 1 and it is provided with the usual chuck spindles 2 and 3, the spindles being longitudinally adjustable, one toward and away from the other in the usual manner common to such machines. The chucks 4 and 5 each are provided with offset extensions 6 and 7 for the chuck 1- and f and 9 for the chuck 5.

The extensions or arms are provided with recesses or guide slots 10 into which projects adjusting screws 11 with lock nuts 12. The adjusting screws 11 engage bosses 13 in the offset members or brackets 14 and 15. Each bracket consists of a table-like portion 16 with longitudinal slots 17 and 18 and at the end of each offset member or bracket are lateral wings 19 and 20 with slots 21. therein through which the bolts 22 may pass to engage the chuck so that when the adjusting screw 11 has altected the necessary radial adjustment the bolts 22 may fasten the brackets in adjusted position.

Supported by the brackets l t and 15 is a channel shaped stay-log 23 having bolts 24 and which engage the slots 17 and 18 to e'l'l'ect longitudinal adjustment between the stay log and the bracket members. The flanges 26 and 27 of the stay log carry threaded log engaging pins 28 and 29 to bite into the veneer log 30 so as to hold it fast to the stay 10;; 23. The veneer will be cut from the of? side of the 10;; until a sufficient amount of veneer is moved, then the 10; will be turned and the cut will be made from the side just previously next to the stay log, that is from the near side. Therefore practically all of the log can be used for veneer.

According to my invention the log will not necessarily be marred in any way or require any part to be cut away in order to fasten it to the stay log, so I have provided a convenient inexpensive construction 01 stay log adapted to be associated with the chucks of the veneering machine. The only alteration necessary is the substitution of the chucks with the arms or projections in lieu of the normal chucks and the application of the brackets and normal form of stay log. The veneer cuts are made cccentrically from the log, as is shown in Fig. 4 and when one side is out far enough toward the center of the log, the part ust cut'is turned toward the pins 28 and 29 which now engage it so the cuts can be made from the portion pre' viously engaged by the pins.

I have not described how the chucks are moved toward and away one from the other, because this is common mechanical construction and the mechanism for adjusting the chucks is one with which any one skilled in the art is familiar.

lVhat I claim and desire to secure by Letters Palent is:--

1. In combination, a veneerino; machine including chuck spindles, chucks on the spindles having; radial recesses, brackets having lugs in the recesses, slotted wings on the side edges of the brackets, radial adjusting screws in the chucks in threaded engagement With the lugs, bolts passing through the slots into the chucks and a stay log supported by the brackets.

2. In combination, a veneering machine including chuck spindles, chucks 0n the spindles having radial recesses, brackets having slotted side Wings, lugs on the brackets located in the recesses, adjusting screws in the chucks in threaded engagement with the lugs, means passing through the slots into the chucks to fasten the l rackets to the chucks, longitudinally slotted table portions on the brackets, a stay log, and means passing through the stay log and the slots in the table portions to fasten the stay log to thetable portions of the brackets.

In testimony whereof I affix my signature.

CLARENCE A. KESSLER.
